I had the most awesome opportunity recently to visit a lesser-known, but great tourist attraction. I got to visit the National Cryptologic Museum, which is practically a stone’s throw from where I live in Columbia, MD.

I joined a group that I found through an online meetup that had arranged for a guided tour.

Here are some of the highlights of our visit, in the following photos.

This was in the lobby. By the time I figured out how it worked, the tour had started! 🙂
